Brief description

The TZIDC-200 is an electronically configurable positioner with

communication capabilities designed for mounting to

pneumatic linear or part-turn actuators. It features a small and

compact design, a modular construction, and an excellent

cost-performance ratio.

Fully automatic determination of the control parameters and

adaptation to the final control element yield considerable time

savings and an optimal control behavior.

Pneumatics

An I/P module with subsequent pneumatic amplifier is used to

control the pneumatic actuator. The well-proven I/P module

proportionally converts the permanent electrical setpoint signal

from the CPU into a pneumatic signal used to adjust a 3/3 way valve.

The air flow for pressurizing or depressurizing the actuator is

continuously adjusted. As a result, excellent control is

achieved. When reaching the setpoint, the 3/3-way valve is

closed in center position to minimize the air consumption.

Four different pneumatics versions are available: for single

acting or double-acting actuators, each with “fail-safe” or “fail freeze” function.
